Answer:
0.31 yr
Step-by-step explanation:
The formula for interest compounded continuously is

FV = future value, and
PV = present value
If FV is twice the PV, we can calculate the doubling time, t

1. Brianna's doubling time

2. Adam's doubling time
The formula for interest compounded periodically is

where
n = the number of payments per year
If FV is twice the PV, we can calculate the doubling time.

3. Brianna's doubling time vs Adam's
10.663 - 10.355 = 0.31 yr
It would take 0.31 yr longer for Brianna's money to double than Adam's.

Answer:
By a quick online search, i found two tape diagrams:
13) You: -
Friend: - -
So you have one block, and your friend has two.
We know that you work for 3 hours, this means that your only block must represent 3 hours.
And all the blocks represent the same amount of time, then each one of the two blocks of your friend also represents 3 hours.
Then in total, he tutored for 3 hours + 3 hours = 6 hours.
14) You: -
Friend: - - - - -
In this case, you still have only one block, but now your friend has 5.
Using the same reasoning as above, we can conclude that each block represents 3 hours, and your friend has 5 of them, this means that he tutored for:
5*3 hours = 15 hours
The Answer to the problem is X=3 because sice it is equidistant you do 2x+24 = 30 and subtract 24 from 30 then you will get 2x=6 tben you divide 2 frkm both sides and you will have x=3
